[back-formation from hairy] The
complications that make something hairy. "Decoding TECO
commands requires a certain amount of hair." Often seen in the
phrase `infinite hair', which connotes extreme complexity. Also
in `hairiferous' (tending to promote hair growth): "GNUMACS
elisp encourages lusers to write complex editing modes." "Yeah,
it's pretty hairiferous all right." (or just: "Hair squared!")
